General information on sharpening cutting teeth
• Never use a blunt chain. When the chain is blunt you
have to exert more pressure to force the bar through
the wood and the cuttings will be very small. If the
chain is very blunt it will not produce any cuttings at
all. Wood powder would be the only result.
• A sharp chain eats its way through the wood and
produces long, thick cuttings.
• The cutting part of the chain is called the cutting link
and this consists of a cutting tooth (A) and the raker lip
(B). The cutting depth is determined by the difference
in height between the two.
A
B
• When you sharpen a cutting tooth there are four
important factors to remember.

gauge. This will help you obtain the maximum kickback
reduction and cutting performance from your chain.
